6. INSTALL FRONT EXHAUST PIPE ASSEMBLY


    A104634

  1. Using a vernier caliper, measure the free length of the compression springs.

    Minimum Length:
    Item
    		Length
    Front
    		41.5 mm (1.634 in.)

    HINT:
    If the length is not as specified, replace the compression spring.



    A104635E07

  1. Using a plastic hammer and a wooden block, tap in a new exhaust pipe gasket until its surface is flush with the exhaust manifold.

    NOTICE:
    1. Install the gasket in the correct direction.
    2. Do not reuse the gasket.
    3. Do not damage the gasket by dropping it, etc.
    4. Do not damage the outer surface of the gasket.
    5. Do not push in the gasket with the exhaust pipe when connecting it.
    6. After the installation, check that the gaps between the flanges of the exhaust manifold and front exhaust pipe assembly are consistent front-to-rear and left-to-right.

  1. Install the front exhaust pipe assembly to the exhaust manifold with the 2 bolts and the 2 compression springs.

    Torque:
